대형 Dry Screw Vacuum Pump

Excellent corrosive gas and entrained liquid handling capabilities and realizing 10-3torr vacuum degree

▶ Vps dry vacuum pump includes the standard advantage of the P Series(Single Pitch) model and following details (Low ultimate pressure, corrosion resistance, cooling effect, etc.)

  • Low Ultimate Pressure

    The dry vacuum pumps can operate continuously in all the ranges of pressure from atmosphere to the ultimate pressure, and it can reach at 0.0075Torr(1Pa)by itself and has a high efficiency

  • Cooling Effect

    - No Cooling Gas necessary.
    - Unique hydrodynamic spiral jacket structure
    - Reducing discharge temperature greatly & close to T4 requirement

  • Corrosion Resistance Design

    - Suitable for pumping Toxic, Corrosive and condensable gas by special coating(PTFE, PFA, Ni, NIFA, PEEK)
    - Preventing condensation of corrosive gas through lowering vapor pressure by the gas ballast(N2cooling purge)

  • Power Consumption

    - Variable pitch screw design
    - power consumption reduced by 30%

Characteristice of

VPS-C Series Dry Vacuum Pump

Reliable seal structure

  • Mechanical seal and lip seal applied
  • Dry vacuum pump exclusive mechanical seal.
  • Use of air & N2 purge in front of Mech. seal for protection from dust & etc.

    Applid variable pitch screw
  • Prevention of coating damage by pump temperature rise
  • 30% reduction in power consumption by energy-saving design

    Vacuum degree improvement
  • Reaches the maximum vacuum degree 0.0075torr(1Pa)
  • Increase pumping volume from high vacuum
  • Maintains stable volume from atmospheric pressure up to 1torr(133Pa)

    Spiral coolant jacket
  • Excellent cooling efficiency of the spiral jacket
  • Low operating temperature
  • Controlling temperature inside the pump with a small amount of coolant

    Smooth discharge structure
  • Short gas path through the pump make quick gas discharge
  • Smooth condensate draining within the pump
  • Excellent liquid handling ability

    IEC Flange(NEMA Optional)
  • Mostly C-flange design Simplified mounting reduce noise level and eliminate shaft alignment
  • Rib enhancement for deformation and vibration prevention

    Grease leakage prevention
  • Triple single lip seal
  • Applied the optimized grease space

    Material of construction
  • Casing : Ductile Iron(Teflon Coated, PTFE)
  • Screw : Ductile Iron(Teflon Coated, PTFE)
  • Shaft Seals
        - Suction(Rear):Mechanical Seal & Lip Seal
